Ethereum is an open-source, decentralized blockchain that supports smart contracts and decentralized applications (dApps). Unlike Bitcoin, Ethereum functions as a Web3 platform for DeFi, NFTs, and DAOs. Its native asset, Ether (ETH), is used for gas fees, staking, and investment.
In short, Ethereum = Blockchain + Smart Contracts + Ether (ETH).
As the second-largest cryptocurrency by market capitalization, Ethereum has evolved into the most dominant decentralized blockchain protocol supporting smart contracts, DeFi, and real-world asset (RWA) tokenization.
Financial institutions such as Citi Bank project ETH could reach $5,440 by 2026, while Standard Chartered sees potential prices exceeding $7,500. These projections are driven by growing institutional adoption through Spot ETFs and a series of critical network upgrades.
Ethereum’s Advantages
- Largest Ecosystem – Ethereum has the most developers, DeFi projects, NFTs, and dApps.
- Smart Contracts & Flexibility – Anyone can build decentralized applications on Ethereum.
- High Security – Secured by thousands of validators and stable since 2015.
- Widespread Adoption – Used by major companies and supported by ETH ETFs.
- Proof of Stake – Since 2022, energy consumption has dropped by over 99%.
Ethereum’s Drawbacks
- High Transaction Fees – Especially during network congestion.
- Limited Scalability – With transaction speed still a challenge.
- Many Newer Competitors – Offer faster transactions and lower fees.
- Using dApps, Staking, and Wallets – Can be complex for beginners.
- Regulatory Risks – As ETH may be classified as a security in some countries.
History & Development of Ethereum
- 2015 – Ethereum Mainnet Launch: Ethereum officially launched with Ether (ETH).
- 2017 – ICO Boom: Thousands of crypto projects launched using ERC-20. ETH rose from around $8 to over $700.
- 2020 – DeFi Boom: DeFi platforms such as Uniswap, Aave, and Compound grew rapidly, reaching billions in TVL.
- 2021 – NFT Hype: Ethereum became the center of the NFT market, with collections like CryptoPunks and Bored Ape Yacht Club.
- 2022 – The Merge: Ethereum transitioned from Proof of Work (PoW) to Proof of Stake (PoS), cutting energy usage by 99.95%.
- 2024 – Spot ETH ETF Approval: The U.S. approved the first Ethereum ETF, boosting legitimacy and institutional access.
- 2024 – Dencun Upgrade: Ethereum launched the Dencun upgrade with proto-danksharding (EIP-4844).
- 2025 – Pectra Upgrade: Aims to improve scalability, security, and efficiency, including enhanced staking efficiency (EIP-7251), account abstraction (EIP-7702), and data efficiency (EIP-7691).
During the 2015 ICO, ETH was priced at around $0.75 per coin. Today, its value has increased thousands of times.
Unlike Bitcoin, which has a fixed supply of 21 million coins, Ethereum has no strict maximum supply. However, since the implementation of EIP-1559, a portion of ETH is burned with every transaction, helping control the circulating supply.
What Is Ethereum Used For?
- Smart Contracts & dApps – Developers can build applications and smart contracts without intermediaries.
- Asset Tokenization – Supports ERC-20, ERC-721, and real-world asset tokens.
- DeFi Infrastructure – Foundation for decentralized finance services such as lending, staking, DEXs, and yield farming.
- DAOs – Community-led organizations governed by token-based voting.
- Interoperability & Layer 2 – Solutions like Optimism, Arbitrum, and zkSync improve speed and cross-chain connectivity.
How Ethereum Works
Ethereum uses a blockchain, a decentralized digital ledger that records all transactions. Transactions are verified and added to new blocks.
- Block Structure – Contains transactions, timestamps, and a unique hash linking to the previous block.
- Transaction Process – Transactions enter the mempool, are selected by validators, verified, and included in a block.
- Network Nodes – Thousands of nodes worldwide store copies of the blockchain for security and transparency.
- Hashing & Cryptography – Ensure transaction data remains authentic and secure.
Since The Merge in September 2022, Ethereum has transitioned from Proof of Work (PoW) to Proof of Stake (PoS), which is over 99.9% more energy efficient.
Proof of Stake (PoS) Consensus
- Validator Selection – Validators are randomly chosen after staking a minimum of 32 ETH or via staking pools.
- Block Creation & Attestation – Selected validators propose blocks, while others confirm them. Once consensus is reached, the block is added.
- Rewards & Penalties – Honest validators earn ETH and gas fees, while malicious behavior can result in penalties such as slashing.
- Finality with Gasper – Ethereum uses the Gasper mechanism to finalize blocks.
Note that Ethereum is the name of the blockchain platform, while Ether (ETH) is its native digital currency. ETH is the token used throughout the Ethereum ecosystem.

Ethereum vs. Bitcoin: Key Differences
1. Main Purpose
- Bitcoin (BTC): Launched in 2009 as the first digital currency to store and transfer value without intermediaries. Primarily a store of value and peer-to-peer payment system.
- Ethereum (ETH): Launched in 2015 as a smart contract platform. ETH acts as “fuel” (gas) to run decentralized applications such as DeFi, NFTs, and DAOs.
2. Blockchain Function
- BTC: Records only financial transactions (sending and receiving BTC).
- ETH: Executes programmable smart contracts, enabling a wide range of applications.
3. Mechanism & Technology
- BTC: Fixed supply of 21 million coins, originally using Proof of Work.
- ETH: No hard supply cap, now using Proof of Stake for greater energy efficiency.
4. Value & Usage
- BTC: Often seen as “digital gold” or a hedge asset.
- ETH: A utility token used for gas fees, validator staking, and investment.
Real-World Use Cases of Ethereum
- DeFi – Platforms like Uniswap enable trading and lending without banks.
- NFTs – Marketplaces like OpenSea support digital art, collectibles, and gaming items.
- Stablecoins – Assets such as USDC and DAI are used for daily transactions and fiat-crypto bridging.
- DAOs – Transparent digital communities governed through token-based voting without central authorities.
The Future of Ethereum
- Pectra Upgrade (2025) – Designed to improve efficiency and staking mechanisms.
- Price Projections – Standard Chartered forecasts ETH could reach USD 7,500 in 2025 and USD 25,000 by 2028, driven by increased adoption.
- Institutional Adoption – Growing participation from major institutions via ETH ETFs and Web3 integrations.
